Question

Transfer of gene between populations that differ genetically from one another is called

• A. Gene mutation
• B. Gene flow
• C. Genetic drift
• D. Genetic recombination

Answer 1

The correct option is B Gene flow

• Gene mutation is any change in the structure of the DNA that results in the addition or deletion of a specific protein coded by that gene i.e. the part of DNA.
• Gene flow is the movement of alleles from one population to another. It is the exchange of genetic material by interbreeding between the individuals within a population or between the populations of the same species.
• Genetic drift is a random change in allele frequencies over the generation. It is brought by chance alone.
• Genetic recombination occurs when there is an exchange of DNA segments of different chromosomes or there may be a rearrangement of DNA sequences which can be due to the breaking or joining of chromosomes.

So, the correct answer is B (Gene Flow).
